You should not hear the "hum of the fuel pump" on turning the key. Rather, you hear the whine of the CD ignition module. The fuel pump does not activate until the motor begins turning on a 79. To hear the difference, take off your air cleaner turn on the ignition switch and push up on the air sensor arm. The fuel pump will come on when you do this. It is a totally different noise from the CD box. This makes me think you have an intermittent CD box problem, probably a loose connection since your narrative points to this.
